Marin briefs: Rivers wins fifth Double Dipsea in a row

Roy Rivers, 53, ran to his fifth Double Dipsea victory in a row Saturday, covering the 15-mile course in a time of 1 hour, 39 minutes, 28 seconds. He had a 14-minute head start in the footrace handicapped by age and gender. Cliff Lentz of Brisbane was second in 1:40.24.

"It was really a perfect day. There were no injuries and no problems," said race director Ken Reed following the 41st running of the trek from Stinson Beach to Mill Valley and back. "The weather was wonderful - foggy and breezy."

San Rafael's Alex Varner, who did not have a head start, had the fastest time and finished third in 1:43.58. Ross resident Melody-Anne Schultz was the first woman, finishing fourth in 1:45.31. Mimi Willard was fifth in 1:47.21

Reed said it was the highest number of paid entries, with 699 people signing up. He said 612 started the race and 573 finished. Following the 100th running of the Dipsea earlier this month, the trail takes a break before the ultra distance Quad Dipsea on Nov. 27.
